HOSE.

- .7b allwhomt mdywncem:

Be it known that. I, Hownnn VR Goomnt, a. citizen of the United States, reeiding at Alden, in the county of Delaware und Stute of Pennsylyafnie, have invented certain: new

. end useful Improvements in Hose, of which `the following 1s a, specification.

1n the manufacture of suction and someV other kinds oi. hose it ie cuetol'nnry to insert between the outer and-inner plies n, met-ul reinforcement .und a. layer of rubber material. 4The lutter does not adhere to the metal. which. is loose so that the enter and inner plies are only `joined together' between the metall reinforcements or,mo1-e accurately,be- `tween the spiral windings of the metal reim foroements, so that in use either under pree,

sure or suction the outer and inner plies, be-

ing joined only at intervule and not Awhere thus increase the efficiency' and din'nbility of the reinforcement occurs, Separate trom ench other. Y l The principal object of the present inifen tion is to avoid this defect and disndven `tege und to join the enter and inner pliee` througln-mt the entire .length thereof ,und

5 QTo this end other ends hereinafter i forth the invention comprises the combination with. the-hose of a. textile o'rfabric en'- yelop surrounding Vand following the ind-ividuul turns" of the spiral metall reine `forcement end Servingwith, the layer of rule-` ber n'mteriulto 0in the outer und ,inner plies j throughoiit their entire length :md to holtfll theindividuulturns of the reinforcement in place, 'anii the invention further comprises the improvements claimed at the end hereof und `described in connection with the accom penying drawings in which* f i FigureV 1, iS a sido View, partly in section, of 'a hose embodying features of the invention,v and Y Fig. 2,. is e similarfview illuetrating e mod'iiication. inthe drawings 1 and 2, are the outer an innerrul-)ber layers or layers of rubber meteriul that are usually applied to the outside Specieetion of Letters Patent. `:[Famelgtel Oct, 15, j il, Appnmmn una. nummer 31; 191:4.l serial, No. 809,715.

and inside ot vthe hose. 3 sind t;v are the outer end inner textile layers as of duck and rub- 50 beror rubber material. Between these inner and outer textile layers there is u metal rein- Afor@ement which is wound spil-ally. This reinforcement muy have an appropriate crossseetion. Aeehown in Fig. 1, the reinforce 55 ment 5, is of circular.cross-section, and ns shown in Fig. 2, the reinforcement. 5*, is of rectangular cross-section. 6, is a layer of rubber or rubber materiel arranged between the yinner and outer textile layers and in' 6l)- which the reinforcement is'embedded. At the pointe or intervals 7, between the reinforcements or the windings of the reinforcement, `theinmaterial G', firmly joins the textileQy layers as by vuleanization. 518, is e` textile' eri-- 1165 volop surrounding the metal reinforcement ,A

Wound, braided or otherwise a p1iedan'd"by thread it isintended 4to indu e material .to which th'erubber layer 6, will adhere as 'by 70 f 'vulcunization .This envelop 8, joinsl the. outer and inner textile layers and thus the latter are connected throughout their length, and while the rubberdoes not vulcenize to the metal of the reinforcement, it does ad-` 75 here to the covering or envelop. By the d cscribed construction, although the reinforceaA ment is not vulcanized to its co ver,`"still it is heldin place thereby andthe,cove1 \,is iml-A i canized and joined to the vinne;`l and outernpl .textile layer," so that it seryesto connectV tiem,
